Something like half of the top 10 games on Steam can't even start due to anti cheat and Steam is what's pushing gaming on Linux. To be fair to them if they weren't that number would be a lot worse, many of their own games are in that list. Of the ones that can they generally work alright but a few have intermittent crashes or things you have to workaround.

If you play older/smaller single player games though it generally does the job pretty darn well.

Almost any online game will not work because of anticheat software designed specifically for windows.

I personally just decided to give up on the online games instead.

Xbox, Geforce Now and Stadia streaming etc are another option.
